• Undertake functional design activities, modelling and analysis.
• Produce design documentation, Verification & Validation evidence, and safety justifications.
• Support specification qualification and procurement of components, working collaboratively with suppliers.
• Engage with stakeholders across the cross‑functional project team.
• Drive engineering governance through peer reviews and design reviews.

• Strong experience designing hydraulic/mechanical systems – ideally in complex, safety‑critical environments such as maritime, aerospace, defence, nuclear, oil & gas, and sub‑sea.
• Familiarity with systems and equipment such as hydraulic power units (HPUs), variable frequency drives (VFDs), control cabinets, pumps, electric motors, hydraulic actuators, hydro‑static transmissions, and fluid mechanics.
• Proven capability in system lifecycle delivery from concept through to commissioning.
• Demonstrated leadership through technical direction, mentoring, or project ownership.
• Chartered engineer or working towards professional accreditation.

• Familiarity with design standards such as ASME, BS EN, and other applicable standards.
• Previous engagement with suppliers or stakeholders on hydraulic/mechanical systems, including control logic (e.g., Variable Frequency Drive solutions).

Join a dynamic, multidisciplinary engineering team to help deliver critical mechanical capability at the heart of a high‑profile programme. Collaborate closely with suppliers, systems engineers, and key stakeholders to shape high‑integrity technical solutions, support team growth, and keep projects on technical and financial course. This role grows with you in areas such as technical leadership, people leadership, or specialist technical delivery, providing flexibility to shape impact and influence the future of mechanical engineering excellence.
